THE FACTS NEVER KNOWN ABOUT SPACE.

1) No Fact Here!!!!😁😁

2) The Earth’s rotation is gradually slowing.

This deceleration is happening almost imperceptibly, at approximately 17 milliseconds per hundred years, although the rate at which it occurs is not perfectly uniform. This has the effect of lengthening our days, but it happens so slowly that it could be as much as 140 million years before the length of a day will have increased to 25 hours.

3) The Earth was once believed to be the centre of the universe.

Due to the apparent movements of the Sun and planets in relation to their viewpoint, ancient scientists insisted that the Earth remained static, whilst other celestial bodies travelled in circular orbits around it. Eventually, the view that the Sun was at the centre of the universe was postulated by Copernicus, though this is also not the case.

4)Venus is often called the Earth’s sister planet. 

The Earth and Venus are very similar in size with only a 638 km difference in diameter and Venus having 81.5% of the Earth’s mass. Both also have a central core, a molten mantle and a crust.

5)Atmospheric pressure on Venus is 92 times greater than the Earth’s. 

Due to this crushing small asteroids when they enter its atmosphere Venus has not small craters. The pressure felt on Venus’ surface is equivalent to that deep beneath the sea on Earth.

6)Jupiter has the shortest day of all the planets.

It turns on its axis once every 9 hours and 55 minutes. The rapid rotation flattens the planet slightly, giving it an oblate shape.

7)Saturn is the flattest planet.

Its polar diameter is 90% of its equatorial diameter, this is due to its low density and fast rotation. Saturn turns on its axis once every 10 hours and 34 minutes giving it the second-shortest day of any of the solar system’s planets.

8)Saturn has more moons than any other planet.

20 new moons were discovered in 2019 bring the total to 82, 3 more than Jupiter.

9)Uranus makes one trip around the Sun every 84 Earth years.

During some parts of its orbit one or the other of its poles point directly at the Sun and get about 42 years of direct sunlight. The rest of the time they are in darkness.

10)Uranus was officially discovered by Sir William Herschel in 1781.

It is too dim to have been seen by the ancients. At first Herschel thought it was a comet, but several years later it was confirmed as a planet. Herscal tried to have his discovery named “Georgian Sidus” after King George III. The name Uranus was suggested by astronomer Johann Bode. The name comes from the ancient Greek deity Ouranos.
